| 08:13 | <Hyperbyte> Does it matter for LTSP performance what kind of graphical card (GPU) the server has?

| 08:25 | <Hyperbyte> Didn't think so
| |
| 08:25 | LTSP's performance with java applications (firefox, to name one) on my setup is horrible.
| |
| 08:25 | gorkhaan has quit IRC | |
| 08:27 | <Hyperbyte> Thinking about replacing the onboard network card (Realtek) with an Intel Pro one
| |
| 08:27 | Maybe someone has some other suggestions I could try first?
| |
| 08:28 | Gadi has joined #ltsp | |
| 08:31 | <Appiah> I feel that way about my desktop
| |
| 08:31 | java applications being slow :D
| |
| 08:32 | well java and/or flash with browser is always ... bad?
| |
| 08:32 | are you running 64bit or 32bit on the server?
| |
| 08:34 | gorkhaan has joined #ltsp | |
| 08:42 | dlezcano has quit IRC | |
| 08:47 | nubae has quit IRC | |
| 08:53 | <Hyperbyte> 64bit on server, 32bit on client
| |
| 08:54 | But I'm not talking about the browser plugins java/flash
| |
| 08:54 | I mean the whole Firefox application
| |
| 08:54 | For example, it stutters a little while scrolling
| |

| |
| 08:56 | <buffalosolja> is the ltsp-build-client.conf file supposed to be in the etc/ltsp by default in the Atlernative LTSP installation for Ubuntu 10.04?

| 09:07 | <alkisg> ^^ Hyperbyte
| |
| 09:07 | vongrippen has joined #ltsp | |
| 09:08 | <alkisg> buffalosolja: you mean after the installation? No such file should exist by default, but you want to create one, that's the right place.

| 12:30 | <eXcAliBuR> what is the latest version of fedora that works nicely with ltsp 5?
| |
| 12:32 | <vagrantc> development on fedora was stalled for a while ... but someone new picked it up. not sure if they frequent irc or not
| |
| 12:32 | <eXcAliBuR> okies
| |
| 12:32 | which would u run ltsp on?
| |
| 12:32 | fedora or ubuntu
| |
| 12:32 | ?
| |
| 12:33 | <vagrantc> there are some list posts to ltsp-discuss@lists.sourceforge.net
| |
| 12:33 | <eXcAliBuR> it's for classroom enviroment
| |
| 12:33 | <vagrantc> none of the above, i'm a debian loyalist :)
| |
| 12:33 | though if i were forced against my will to choose between fedora and ubuntu, i'd pick ubuntu :)
| |
| 12:34 | <Gadi> heh, debian loyalist
| |
| 12:34 | <vagrantc> it's had active development, and a lot of users
| |
| 12:35 | <eXcAliBuR> hmmm debian often gets overlooked
| |
| 12:35 | does it have a perty look and feel to it?
| |
| 12:35 | <vagrantc> it's not as glossy as ubuntu, for sure.
| |
| 12:36 | most of the software is nearly identical, though
| |
| 12:37 | some significant differences in LTSP implementation
| |
| 12:37 | defaulting to NFS (debian) and NBD (ubuntu)
| |
| 12:37 | <eXcAliBuR> oh this is worse then shopping
| |
| 12:38 | how will i choose
| |
| 12:38 | :{
| |
| 12:39 | <vagrantc> pick what you're most comfortable with, try it out... if you don't like it, try something else
| |
| 12:39 | <eXcAliBuR> i'm comfy wit ubuntu, but only for servers ... command line stuff
| |
| 12:39 | i don't like it's gui
| |
| 12:39 | <vagrantc> what do you want in a gui?
| |
| 12:40 | i'm really happy with Debian using LXDE for a GUI.
| |
| 12:40 | LXDE is nice and lightweight, yet pretty featureful ... perfect for a multi-user LTSP server.
| |
| 12:42 | <eXcAliBuR> does debian have nice effects when u move windows and stuff?
| |
| 12:45 | <vagrantc> that depends on your window manager and client hardware
| |
| 12:46 | debian has hundreds of window managers to choose from
| |
| 12:46 | default install typically comes with gnome, just like ubuntu
| |
| 12:47 | <eXcAliBuR> ummm there is cd and dvd
| |
| 12:47 | but it doesn't tell me the difference
| |
| 12:47 | what do i download
| |
| 12:49 | <vagrantc> depends on your internet connection ... if you will be installing with a decent interenet connection, i'd recommend going with the CD or the netinst CD ... if you want to install without network access, then probably the DVD
| |
| 12:49 | because then it will download the current packages off the network ... rather than get older packages off the DVD

| 13:02 | * alkisg wonders if we'll be able to use BTRFS snapshots to serve LTSP clients and get rid of both NFS + NBD :) | |
| 13:02 | <vagrantc> alkisg: over the network?
| |
| 13:02 | <alkisg> Yup
| |
| 13:02 | <vagrantc> crazy.
| |
| 13:03 | it seems like btrfs aims to do *everything*
| |
| 13:03 | <alkisg> There's a separate descenant of btrfs for over the network file systems, but I'm not talking about that
| |
| 13:03 | <Ghid0rah> what advantages does it offer over the latter?
| |
| 13:04 | <alkisg> I hope that the admin will be able to change files in the chroot and the clients would pick them up on the next reboot, when they get the new snapshot...
| |
| 13:05 | ...and possibly fat clients could use the whole server /
| |
| 13:05 | <Ghid0rah> oh neat
| |
| 13:05 | * vagrantc *hates* the idea of exporting / | |
| 13:05 | <eXcAliBuR> i want to export myself somewhere warm
| |
| 13:06 | <vagrantc> too many potential: "*oops* that shouldn't have gone over the wire!"
| |
| 13:06 | johnny has joined #ltsp | |
| 13:06 | <alkisg> Teachers here wouldn't give a damn about security if they could just install stuff with synaptic on the server, and have them on their fat clients on the next reboot
| |
| 13:06 | johnny has quit IRC | |
| 13:06 | <Ghid0rah> you allow teachers to install stuff?
| |
| 13:07 | <alkisg> teachers == admins here, we don't have any technicians in schools
| |
| 13:07 | They alone install their labs
| |
| 13:07 | <Ghid0rah> oh interesting
| |
| 13:07 | are you state side?
| |
| 13:07 | <alkisg> A little eastern... about half a globe :)
| |
| 13:07 | Greece
| |
| 13:08 | <Ghid0rah> Do you filter student access?
| |
| 13:08 | internet access that is
| |
| 13:08 | <vagrantc> people don't give a damn until suddenly a clever student gains root on the servers and repeatedly changes their grades...
| |
| 13:08 | <alkisg> Some of the teachers do, with squid
| |
| 13:08 | The grades aren't on the ltsp servers, of course :)
| |
| 13:08 | <Ghid0rah> so the teachers do everything
| |
| 13:08 | <alkisg> Yup
| |
| 13:08 | <Ghid0rah> wow
| |
| 13:09 | <vagrantc> alkisg: and they don't access them via the servers?
| |
| 13:09 | <alkisg> No, they use some filthy windows-only software which doesn't even work
| |
| 13:09 | <Ghid0rah> what softwareis that
| |
| 13:09 | dlezcano has joined #ltsp | |
| 13:10 | <alkisg> So we still have to use paper for grades, the electronic system is just a helper
| |
| 13:10 | <Ghid0rah> so advanced with teachers
| |
| 13:10 | <alkisg> It's a greek-only software called e-school, noone likes that
| |
| 13:11 | tastle73 has joined #ltsp | |
| 13:12 | <tastle73> hi, I have a 10 workstation 10.04 ubuntu based ltsp 5 installation with a small gnome problem
| |
| 13:12 | <Ghid0rah> what problem are you havingt?
| |
| 13:12 | <tastle73> hi, I am trying to set the screensaver timeout
| |
| 13:12 | I am using gconf-editor and setting mandatory with seemingly no effect
| |
| 13:14 | <Ghid0rah> hrmm
| |
| 13:14 | I used this to shut off the screen saver
| |
| 13:14 | gconftool-2 --type boolean -s /apps/gnome_settings_daemon/screensaver/start_screensaver false
| |
| 13:18 | <tastle73> thank you. I just applied that, hopefully it works!
| |
| 13:18 | * alkisg thinks that's for the current user only | |
| 13:21 | <tastle73> doesn't see a global variable for that either
| |
| 13:21 | <alkisg> You can put it as a mandatory setting from gconf-editor, though
| |
| 13:22 | <vagrantc> apparently mandatory settings require a fairly recent version of gcon-2 ?
| |
| 13:23 | <tastle73> I don't have a subsetting of gnome-_settings_daemon of screensaver
| |
| 13:23 | dlezcano has quit IRC | |
| 13:24 | <alkisg> vagrantc: no, they work fine here
| |
| 13:25 | <vagrantc> alkisg: on lucid, or earlier versions?
| |
| 13:25 | * alkisg thinks the settings are on /apps/gnome-screensaver, though | |
| 13:26 | * vagrantc counts lucid as "fairly recent" | |
| 13:26 | <alkisg> vagrantc: I think I first tried the mandatory in 8.04, but gconf-editor didn't have policykit integration until lucid. I think it was running in karmic with "sudo gconf-editor" for mandatory settings, though
| |
| 13:26 | <vagrantc> unless ubuntu had it patched in for a long time...
| |
| 13:27 | i just ended up using non-mandatory defaults for maximum backportability
| |
| 13:27 | <alkisg> But /etc/gconf/gconf.xml* were working from the first time I tried them, I think in 8.04...
| |
| 13:28 | tastle73: so try setting mandatory settings from gnome-editor for this key: /apps/gnome-screensaver/idle_delay
| |
| 13:28 | Ghid0rah has quit IRC | |
| 13:28 | <alkisg> (users need to logoff to get the mandatory settings)

| |
| 14:01 | any suggestions
| |
| 14:01 | I edited the dhcpd file to say fat64

| 15:19 | <robehend1> hey all. I'm getting all kinds of "General Input/Output" errors with OpenOffice running on Ubuntu 10.04 ltsp. Any ideas?
| |
| 15:23 | ogra_ac has joined #ltsp | |
| 15:24 | <robehend1> Also, does anyone know how to make a "Logout" button in the menus? I dont want to use the logout panel applet, as it tends not to stay in the same place across different monitors, I've found. Figured if I could add it to the menu, it'd be golden.
| |
| 15:24 | <alkisg> Check your network? Disable nbd_proxy?
| |
| 15:24 | For a logout menu, one command is "gnome-session-save --logout"
| |
| 15:25 | <robehend1> alkisg: Where am I killing this nbd_proxY/

| |
| 15:27 | <alkisg> man gnome-session-save :)
| |
| 15:27 | (--logout-dialog)
| |
| 15:29 | <robehend1> alkisg: Thankee. I'd man it, but I'm running through my phone on an vnc'd connection. Difficult enough haha
| |
| 15:37 | alkisg: How do I apply the patch in that bug? I can see the code, just not exactly sure what to do with it
| |
| 15:37 | <alkisg> OK let me post some instructions for Lucid in the bug report...
| |
| 15:38 | <robehend1> alkisg: Thanks!
| |
| 15:43 | dafreyg has quit IRC | |
| 15:47 | <alkisg> robehend1: what does this give you? grep BOOTPROMPT /etc/ltsp/ltsp-update-image.conf
| |
| 15:53 | <robehend1> alkisg: let me take a look
| |
| 15:53 | <alkisg> Nothing?
| |
| 15:53 | <robehend1> alkisg: Running it now, had to step away for a minute, student
| |
| 15:53 | alkisg: And yes, nothing
| |
| 15:56 | <alkisg> robehend1: ok, posted to the bug report.
| |
| 15:56 | <robehend1> alkisg: I see that, thanks again. Hopefully this fixes my open office problem. Think it'll help speed up logins as well?
| |
| 15:57 | <alkisg> I don't know about speed, it depends on a lot of things. It did make a difference on my ancient clients though.
| |
| 15:58 | <robehend1> alkisg: How ancient? I'm on p4's with 512 ram.
| |
| 15:59 | <alkisg> On some labs we have celerons @400MHz / 64MB RAM :)

| 16:06 | <robehend1> alkisg: Wow, that's enough to load the ramdisk? I'm also running local firefox for the flash, so I need a bit of overhead to them
| |
| 16:06 | <alkisg> Some tweaking was needed, Lucid doesn't work out of the box with 64 RAM, in needs about 80.
| |
| 16:06 | But after the tweaking everything's fine and running fast :)

| |

| |
| 16:10 | We're using plain thin clients with < 500 RAM and plain fat clients with > 500.
| |
| 16:10 | <robehend1> alkisg: Nice. My kids require flash, sadly, so I have to give them local firefox. By god if they couldn't play Monkey Jump..

| 16:11 | <robehend1> alkisg: Well, since you seem to be a fount of knowledge, here's one I googled a bit but didnt find an answer to: Can I change the Ubuntu splash screen at boot? Not turn it off, but change it?
| |
| 16:11 | <alkisg> No idea, but that isn't LTSP related, you should ask in #ubuntu about it
| |
| 16:12 | <robehend1> alkisg: Ah, that makes sense. Figured it'd be nice, since my students are flipping out that it's "Not Windows!"
| |
| 16:15 | alkisg: In your how-to, it states to edit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg Do you mean pxelinux.cfg/default? Since pxelinux.cfg is a dir?

| 20:37 | <Gibby> i have been googling for about an hour, is there a way to build multiple "PXE" boot options with ltsp-build-client? essentially so a user could chose which image they want or it times out to a default?
